Let's break down the given expression step by step to solve it:

First, let's simplify the expression inside the parentheses:

54 + 3 3/8 4/9
= 54 + (33/8 4/9)
= 54 + (33 4) / (8 9)
= 54 + 132 / 72

Next, let's simplify the second part of the expression:

5 + 1 - 2 + 8
= 6

So now we have:

(54 + 132/72) / 6

To simplify this further, let's first convert 132/72 to a mixed number:

132 divided by 72 equals 1 with a remainder of 60. So 132/72 can be expressed as 1 60/72, which simplifies to 1 5/6.

Now we can rewrite the expression as:

(54 + 1 5/6) / 6
= (54 + 1 + 5/6) / 6
= (55 + 5/6) / 6
= (55 * 6 + 5) / 6
= (330 + 5) / 6
= 335 / 6
= 55.83

Therefore, the final answer is 55.83.
